PROFIsafe Field Device Development

PROFIsafe is a globally leading, integrated technology (IEC 61508 compliant) for fail-safe communication in production and process automation. It is a vendor-independent, open standard developed by a global network of experts within the framework of PROFIBUS & PROFINET International (PI). PROFIsafe has been established as an international standard (IEC 61784-3-3) for years and has the greatest range of products and services for safety applications.

PROFIsafe Highlights

  • Devices can use PROFIsafe to communicate with safety controllers PROFIBUS or PROFINET so that they can be used in safety-related automation tasks to PL e according to ISO 13849-1 or SIL3 (Safety Integrity Level) to IEC 61508.

  • Standard and safety-related communication can be transmitted on the same bus cable with PROFIBUS or PROFINET with PROFIsafe profile.

  • High flexibility when installing or expanding existing installations (retrofit).

  • The PROFIsafe protocol works according to the "Black Channel" principle and is independent of the respective transmission channel (can use copper cable, fiber optics, backplane bus or wireless).

  • PROFIsafe uses proven procedures, such as testing and certification, or the guidelines for installation and thus ensures a high level of availability. Certified PROFIsafe devices therefore simplify the safety-related inspection of equipment
